# long-load

A simple node.js app that mocks up an application with a long start time.

Starts up the server after a configurable amount of time by waiting `START_DELAY` milliseconds.

## Usage

Intended to build with Podman (though Docker should work fine):

```sh

$ podman build . -t long-load

```

Start the container by binding to port 3000 in the container.

```sh

$ podman run --name long-load -p 3000:3000 long-load

```

## Options

`long-load` responds to the following environment variables:

* `START_DELAY`: How long to wait (in ms) before "starting".

Defaults to `1000`.

* `SHOW_HOST`: Whether to prefix replies with the hostname.

Set to `"true"` to enable (quotes required).

Must have hostname located in UTF-8 encoded file `/etc/hostname`.

## Routes

Note that all routes are of type GET for simplicity, even if they really should be something else.

### `/ping`

Replies with 'pong'.

### `/health`

Used as a health probe.

Replies with appropriate error if the app is either sick or still starting.

### `/togglesick`

Toggles whether the app is currently healthy or sick.

### `/hiccup?time=10`

Sets the app as sick for `time` seconds.

Defaults to 10 seconds if `time` is not provided.

Overrides any previously toggled health status.

### `/destruct`

Kills the process with an error code.

Helps for simulating process crashes.

### `/leak`

USE WITH CAUTION.

Consumes a fixed amount of memory (~480MB).

### `/unleak`

Releases memory consumed with `/leak`.

Might not work on all systems, as it tries to force a full garbage collection cycle.
